Form gages and form gaging systems are used to inspect parameters such as roundness, angularity, squareness, straightness, flatness, runout, taper and concentricity.
Polishers and buffing machines are used to impart a fine (low Ra) surface finish on the exterior of a part. To improve surface finish, they use use abrasive grain slurries or compounds on buffs, bobs, cloth naps, laps, very fine grit nonwovens, and coated abrasives.
Specialty grinding and finishing machines include specialized equipment for specific applications such as thread grinding, substrate planarization and optics manufacturing.
Surface metrology equipment is used to measure the surface finish and/or geometry of engineering components. Surface texture and topology characteristics include surface roughness, contour, form, waviness and defects.
